MARTIN S. MIGHAELIS, OF BENTON, LOUISIANA.

COTTON-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 270,824, dated January16, 1883,

Application filed July 25, 1882. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN S. MIOHAELIS,

' of Benton, in the parish of Bossier and State a greater or less numberof plants in the stand,

as desired.

The invention also consists of the construction, arrangement, andcombination of parts, all as hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a plow having my new and improvedcotton-chopper attached thereto. Fig.2 is a sectional elevation of thebell-shaped cutter. Fig. 3 is a plan view of the under side of thecutter, showing the position of the adjustable knife, and Fig. 4 is aplan view of the crank secured to the upper end of the shaft G of thecutter.

A represents the plow, which may be ot'any approved construction.

B represents the cutter, which is by preference made bell-shaped, and isformed with the slotG; and D is the drive-wheel, attached near to theforward end of the beam of the plow; and E represents the adjustableknife, placed inside of the cutter, and F is the connecting rod thatconnects the crank d of the drive wheel with the crank f of the shaft Gof the cutter. The cutter is attached to the plow by means of thejournal-plates h h, in which the shaft G of the cutter is journaled ator near its upper end, and the rearwardly-extending plate or bar J,which is formed with a socket near its rear end to receive the lower endor point, of the shaft G, as shown in Fig. 2. The plates h h are securedto the rear end of the beam of the plow by means of the band H, or anyother similar means may be used, and the rearwardly-extending bar, J isbolted or othplow without the cutter attached.

of the plow. When the cutter is put in place it should be so arranged inthe plates h h and rod or plate Jthat the slot 0 will stand toward theleft side of the plow.

By the means described for attaching the colter it will be seen that theshaft G of the cutter will be held in line with the landside of theplow, so that one-half'of the diameter of the cutter will reach outsideof the plow to the left, and will reach over the row of plants beingchopped-out..

In use, the rows or drills of cotton are first furrowed off along oneside by the plow, or a The cutter is then attached to the plow, and theplow is run along the other or unfurrowed side of the rows. The cutter,reaching over the row, will cut out all of the plants in the row untilthe slot G is brought by the rotary reciprocating movement which thecutter receives from the drive-wheel in line with the row of plants.When in this position the cutter will skip the plants in the row untilit is turned back so that the slot 0 is no longer in line with the row,when the cutter will again out all of the plants in the row. The cutterhaving a regular rotary reciprocating motion, the plants will be skippedregularly, making bills at regular intervals along the row, providedwith standing plants opposite the slot 0 in the rotary reciprocatingmovement of the cutter B.

The distance between the hills may be increased or diminished, asdesired, by changing the connecting-rod F in the series of holes 71 madein the crank F. The rod or plate J is braced by the rod T, reaching fromnear its outer or near end to the mold-board or share of'the plow, asshown in Fig. 1.

The knife E is secured to the cutter by the bolts e e passing throughthe slots 0 e in the knife. These slots adapt the knife to be adjustedfor closing more or less the slot 0 in the cutter, so that the colterwill skip a greater or less number of plants, as desired.

Having thus fully described my invention, I
